STATE PATET IMPROVEMENT IN STOVES.

Specification forming part of Letters Patent N o. 177,272, dated May 9,1876; application filed Apri 6, 1876.

To all whom it may c0ncern:

Be it known that I, ANDREW A. PTz, of Vienna, Empire of Austria, haveinvented a new and useful Improvement in Furnaces and Stoves, whichimprovement is fully set forth in the following specification, referencebeing had tothe accompanyin r drawing, in which- Figure l represents avertical central section of my improvement applied to a boiler. Fig. 2is a horizontal section in the line x w, Fig. 1. Fig. 3 shows myimprovement applied to a heating-stove. Fig. 4 shows it applied to acooking-stove.

Similar letters indicate corresponding parts.

My invention relates to a certain novel arrangement of parts, which isapplicable to furnaces as Well as stoves 5 and the invention consists inthe combination, in a furnace or stove, of a flue for carrying ott' theproducts of combustion, a fuel-magazine, and a basketgrate arranged atthe mouth of said tlue, and constructed to have a vertical and aswinging motion imparted to it, for the object herein` afterspecifically described.

The invention also consists of certain other improvements in theconstruction and arrangement of parts, which will bc fully described,and specifically pointed out in the claims.

In the drawing, the letter A designates a grate arranged according to myinvention. This grate has the form ot' a basket, and is similar in formto an ordinary tire-place grate, ,being open at the top and also partlyat the side. 'lhe letter B-designates a flue, at the mouth of which thegrate is situated, the grate being so placed that the open part of itsside faces this flue. It is obvious that this flue vB may lead under asteam-boiler, C, as

shownl in Fig. l, or through a heating-stove,

as seen in Fig. 3, or through a cooking-stove, as represented in Fig. 4.The grate is attached to a frame, D, which is hinged as at a, andthereby the grate is made susceptible of being swung outward for thepurpose of clearing it of cinders, &c. The frame D, which supports thegrate, is hinged to the wall ot' a magazine, E, a part of which wall isto this end made to project downward beyond the point of the grate, asat E. (See Fig. l.) The grate is thus brought under the lower and openend ot' the magazine E, and, if the maga-zine is filled with fuel,.thegrate is kept constantly supplied therewith. The downwardly-projectingpart E of thc magazine is provided with an opening, b, opposite to thegrate, for

the passage of the products of combustion to.

the line B. The upper end of the magazine E is closed by a cover, F,which is made airtight, so as to prevent the escape of smoke or gases.The magazine is placed ina -vertical way,77 G, and arranged to move upand down in this way, while the way is made to form a part of thefurnace or stove to which the whole may be applied. The magazine and theway are connected together by a screw, H, working in brackets I I, whichlare VaflXed to these parts respectively 5 but, if seen tit, alever,rack, and pinion or other contrivance may be substituted for the screw.It is obvious that, by turning the screw H in one or the otherdirection, the magazine Eis moved up or down, while the grate A partakesof such movement, and hence can thereby be adjusted in any desiredposition with relation to the liue B. By this adjustment ofthe grate Iam enabled to regulate the amount of live lire contained in it at anytime, and, as a consequence thereof, to regulate the quantity of fuelconsumed, inasmuch as, accord-ing to the area of the grate presented tothe flue, a greater or less quantity of fuel is brought under the scopeof the draft. By placing the grate at the mouth of the flue B, whetheror not it is made adjustable, a very effective draft is obtained, whilethe draft is conducted through live lire, and the smoke is consumed.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a furnace or stove, the combination of a Hue, B, for carrying oft'the products of combustion, a magazine, E, and a basket grate, A,arranged at the mouth of said iiue, and constructed to have a verticaland a swinging motion imparted thereto, substantially as andfor theobject specified.

2h In combination with the grate A and Hue B, a magazine, E, to thelower and open end ot' which the grate is affixed, andan adjustingscrew, H, or other equivalent device, the whole being' adapted tooperate substantially as described.
